Alstroemeria plant variety named `Staprimil`

ABSTRACT

A new and distinct Alstroemeria plant variety producing flowers of good quality and attractive coloration, suitable for growing in pots.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety ofAlstroemeria originated as a seedling by crossing as seed parent anunreleased, unpatented seedling identified as 87D1262-5 and as pollenparent an unreleased, unpatented seedling identified as 89G1041-01 fromamong my collection of Alstroemeria seedlings maintained undercontrolled conditions in a greenhouse at Van Staaveren B.V., Aalsmeer,The Netherlands, for developmental purposes. The varietal denominationof the new variety is `Staprimil`.

The first act of asexual reproduction of `Staprimil` was in Aalsmeer,The Netherlands, by propagation by dividing rootstocks. Asexualreproduction in Aalsmeer, The Netherlands, through successivegenerations has demonstrated that the combination of characteristics asherein disclosed for `Staprimil` are firmly fixed and retained throughsuccessive generations of asexual reproduction.

`Staprimil` has not been observed under all possible environmentalconditions. Phenotypic expression may vary with variations inenvironment such as temperature, light intensity, day length and growingand cultural conditions.

Comparison with `Staprilan`, application Ser. No. 08/716.499.

The new variety `Staprimil` differs from the variety `Staprilan` in themain flower color. `Staprimil` is a lighter shade, near 5D than`Staprilan`, the main color of which is near 5C.

SUMMARY OF THE INVENTION

Flowers of the new variety of Alstromeria, `Staprimil` are characterizedby growth and flowers of unusual coloration, as described herein. Thenew variety is especially suitable for growing in pots.
